you can od on water because it dilutes ur blood. Usually happens to runners who drink during their races. they drink a bunch of water, it dilutes their blood, and they become very weak, and show what is normally signs of dehydrtation, so they drink more water and usually end up passing out before they have the chance to die.

anywho...

with the whole OD on THC thing. if it would take your body's weight in thc to overdose, then it's physicxally impossible to overdose. there's no way you could ingest that much, you would literally pop before you got it all in you.

therefore, you cant od on thc.
